Electricity production and distribution in rural areas of some developing countries is one of the main issues for the country to consider. The lack of power generation capacity leaves these countries without cooling, lighting and communications facilities. In the field of telecommunications, wireless networks can easily cover large areas and, in theory, can communicate. However, just like a cell phone needs to be charged for use, so does a computer (like internet access). Access to electricity in developing countries can improve rural living standards and expand business prospects.
In general, the proposed solutions are beyond the equipment and needs of the average rural population. The goal of the solution design was to meet basic communication and lighting needs. They must be very affordable and easy to assemble and operate. They reduce labor and final costs by providing knowledge and creating local jobs.
Often rural electrification includes stand-alone photovoltaic systems. Therefore, the stored energy should be used as efficiently as possible. For lighting, it is necessary to use LED or fluorescent lighting systems. An important advantage of using LEDs for rural electrification is the ability to have efficient light output at DC 12V. This eliminates the need for inverters for the lighting system, making the system cheaper, simpler and actually more reliable. Very importantly, however, obtaining maintenance services in remote areas is a real challenge.
The Nopalu portfolio presented here was made for a rural electrification project in Senegal.
A typical rural electrification lighting system combination scheme is shown in Figure 1. The description of the lighting photovoltaic combination scheme of independent components is shown in Figure 2.
The Nopalu portfolio was designed to design a solution for mobile communication and lighting needs. The solution has up to 5h of dual-lamp lighting and mobile phone charging capability. It is a very compact photovoltaic power generation system composed of multiple products, which can supply power to low-power appliances such as lighting appliances and small appliances that do not require any maintenance, installation and operation. It can also be used as a backup power source or as a main power source to power laptop computers or other systems operating on low DC or AC power.
Due to their high quality, very competitive and low cost, illuminated photovoltaic systems are the ideal solution for power supply in developing countries and any sun-drenched region with low-power stand-alone needs.
Solar or other green energy sources combined with low-power devices, such as LEDs, will ultimately enable developing countries to better access energy in rural areas and enable developed countries to reduce carbon emissions.
The potential of solar energy has been proven and is being used worldwide. The development of renewable energy requires government incentives, but good education is a necessary condition for successful implementation.
